It usually experienced some conditions such as not dissolved, precipitated, fused, absorbed, anorganic, reducer, oxidize, and free metal. One of the heavy metals that can cause negative effects for human and other living creature is Kromium Ion. The waste of the usage of Krom can damage the environment.  Krom is a heavy metal that has dangerous affects that we have to be aware of. Krom (VI) on water was found 2 form od specieses, as an anion (Cr2O7)2- (In Acid solution) and anion (CrO4)2- (In Alkaline solution). One of the ways how to overcome Krom in a waste is by absorb it with an adsorbent, modified Silica DMA. It characterized with an electron microscope scanning, infrared spectrum, K2CrO4 adsorption from liquid solution which investigated in some pH level, contact time, K2CrO4 first concentration. The result of the experiment shows that modifying silica with DMA increases the adsorption capacity for Kromat.

Methods for separating pigments from solvents include coprecipitation and centrifugation. Prussian Blue was created by reacting Fe 3 O 4 with 96% H 2 SO 4 to produce Fe 2+ ions, which were then reacted with K 3 Fe(CN) 6 to produce Prussian Blue. The variation results were referred to as M1, M2, and M3 in this study, which varied three samples of K 3 Fe(CN) 6 . 3.037 mmol K 3 Fe(CN) 6 was reacted at 30.37 mM in sample M1. Sample M2 was made by reacting 9.87 mmol K 3 Fe(CN) 6 30.37 mM with 4.56 mmol FeSO 4 0.018 mM 250 mL. Sample M3 reacted with 12.21 mmol K 3 Fe(CN) 6 at a concentration of 30.37 mM. The M2 sample is the best in terms of K 3 Fe(CN) 6 variation.
